JOHN F. DRIVER, OF WOODBURN, INDIANA.

METALLIC RAILROAD-TIE.

Specification of Letters Patent.

Patented Nov. 4, 1919.

Application filed May 10, 191-8. Serial No. 233,707.

To all whom it may concern:

Be it known that I, JOHN F. DRIVER, a citizen of the United States, residing at Woodburn, in the county of Allen and State of Indiana, have invented new and useful Improvements in Metallic Railroad-Ties, of which the following is a specification.

Relating to railroad ties the invention seeks to provide, as its principal object, a metallic tie formed in the shape of a trough plate, the tie when in use being practically an inverted trough plate.

Another object of the invention is to provide a tie of this character having an arched portion which is provided with corrugations formed transversely thereon.

Still another object of the invention is to provide a tie which is simple and cheap but of durable construction.

Other and further objects will appear as the invention is set forth in detail in the following description.

To the exact construction in which it is shown and described the invention is not to be confined. The actual reduction of practice may show certain changes or alterations to be of advantage and the right is claimed to make any which do not depart from the spirit of the annexed claim. I

In the accompanying drawings:

Figure l is a perspective view of the improved tie with portions of rails attached thereto.

Fig. 2 is a section on a line 2-2 in Fig. 1. Fig. 3 is a section on a line 33in Fig. 1.

Referring to the drawings, there is shown the improved tie which in cross section is similar to the conventional form of a trough the top of the arched portion 1 where seats 5 are formed to receive them, the two seats 5 on any one tie being the requisite distance apart to give the track which is formed by the rails 4 the proper gage. Adjacent the seats 5 and on either side thereof, rectangular shaped apertures 6 are formed and through these apertures the clamping members 7 are designed to pass. The legs 8 of the clamping members 7 have ribs 9 formed on their upper face conforming to and designed to engage the corrugations 2 of the arched portion 1 of the tie. The upper legs 10 of the clamping-members 7 over hang and engage the flanges or bases of the rails 4.

The apertures are of such length that the clamping members 7 may be inserted through them in attaching the rails to the tie, the clamping members initially assuming a position where the body portions stand diagonally with reference to the tie preparatory to the completion of the attachment of the rails to the tie. When the base of the rail is properly positioned on its seat 5, the clamping members 7 are brought into the position shown in Fig. 2, the ribs 9 of the clamping members engaging the corrugation 2 of the tie thus securing the rail in position thereon. Each clamping member is provided with a tongue 11 at the extremity of its leg 8. These tongues 11 are also for engagement with the corrugation 2, as shown in Fig. 2.

Then the rail is placed on the ties as shown in the drawings and the'latter rests upon the ballast, the ballast serves to hold the legs 8 up against the under face of the tie where the ribs 9 and tongues 11 interlock the corrugations 2, thus precluding the disengaging of the clamping members from the tie and from the rail.

The invention having been described what is claimed as new and useful is:

The combination with a metallic railroad tie having an arched portion with corrugations formed transversely therein and further having a rail seat with apertures formed adjacent to the seat, of Z shaped clamping members for insertion through the apertures, the clamping members each hav ing one leg provided with ribs engaging in the corrugations of the arched portion, the remaining leg being engageable with the base of a rail to hold the latter on the seat on the tie.

In testimony whereof I afiix my signature.

JOHN F. DRIVER.
